MicroJIG GRR-Ripper Push Blocks for Table Saw Safety

MicroJIG GRR-Ripper Push Blocks for Safer Table Saw & Router Table Use

The GRR-Ripper is the most versatile push block system available for woodworking machines. Unlike a basic push stick, the GRR-Ripper grips the top of your workpiece from above and to the side simultaneously, providing three-dimensional control over the cut while keeping hands safely away from the blade. It is the standard safety and control tool recommended for table saw ripping, router table profiling, and band saw operations.

The MicroJIG GRRipper 300 Max is the flagship model—designed for stock up to 3½" tall with adjustable legs that adapt to different workpiece widths. The GRR-Rip Smart Hook Push Block adds a trailing hook that catches the workpiece at the end of the cut, preventing kickback and trailing-edge release. For very narrow strips, the GRR-Ripper 1/8" Thin Stock Accessory extends GRR-Ripper capability to strips as narrow as &frac18;".

GRR-Ripper Accessories for Expanded Capability

The modular GRR-Ripper system grows with your needs. The Gravity Heel Kit adds a trailing heel for one-handed stability. The Handle Bridge Kit raises the grip point for use over tall fence setups. Pair the GRR-Ripper with Magswitch magnetic featherboards for full workpiece control, and browse all Shop Essentials including hearing protection for a complete safety setup.

Frequently Asked Questions

What is the MicroJIG GRR-Ripper and how does it work?

The GRR-Ripper is a push block that grips the workpiece from above and from the side simultaneously using adjustable rubber-padded legs. This three-dimensional grip keeps the stock flat on the table and tight against the fence while moving it through the blade, providing much safer control than a standard push stick.

Is the GRR-Ripper safer than a push stick?

Yes, for most ripping operations. A push stick only contacts the trailing end of the workpiece, offering no lateral control. The GRR-Ripper holds the stock vertically, laterally, and longitudinally during the cut, reducing the chance of the workpiece tipping or wandering into the blade.

Can the GRR-Ripper be used on a router table?

Yes. The GRR-Ripper's gripping design works effectively on router tables for edge-profiling and groove-cutting operations where standard push blocks can't maintain consistent downward and lateral pressure simultaneously. It is widely used as a push block on router tables by professional woodworkers.

How narrow a rip can the GRR-Ripper handle?

With the standard GRR-Ripper, narrow rips down to about 1¼" can be handled safely. Adding the 1/8" Thin Stock Accessory extends that capability to strips as narrow as &frac18;", which is far below what most standard push blocks can manage safely.

What is the Gravity Heel Kit for the GRR-Ripper?

The Gravity Heel Kit attaches to the rear of the GRR-Ripper and adds a trailing heel that contacts the back of the workpiece at the end of the cut. This prevents the workpiece from dropping or twisting as it clears the blade, improving safety and cut quality on through-cuts.

Does the GRR-Ripper work on band saws?

Yes. The GRR-Ripper is suitable for band saw use when ripping stock or cutting curves where top-down grip improves control. Its low-profile design fits under most band saw blade guards and provides lateral support not available with a standard push stick.

What other table saw safety accessories does Infinity Tools carry?

Beyond push blocks, Infinity Tools carries Magswitch magnetic featherboards that hold stock against the fence during ripping. Browse Shop Essentials for hearing protection and other safety-related shop products.

Can I use multiple GRR-Ripper accessories together?

Yes. The GRR-Ripper system is modular—the Gravity Heel, Handle Bridge, Deflector Connector, and thin-stock accessories all attach to the main body. Multiple accessories can be combined for operations that require extended reach, different height clearances, or trailing-end control.

Does Infinity Tools offer free shipping on GRR-Ripper products?

Free shipping is available on most orders over the qualifying threshold. See the shipping policies page for current conditions.

Where can I learn proper push block technique for the table saw?

The Infinity Tools learning center covers table saw safety, ripping technique, and proper push block use. Learning correct technique with tools like the GRR-Ripper is as important as having the right equipment.
